TPS25990: TPS25990 thermal evaluation

Part Number: TPS25990

Tool/software:

Hi Expert,

In switch applications, the ambient temperature inside the chassis may be as high as 60°C. In this case, what is the recommended maximum RMS current? Is it reasonable to use RθJA = 19.9°C/W for evaluation? Is there any recommended, evidence-based assessment methods?

Regards,
